MeSH definition : A transferase that catalyzes formation of PHOSPHOCREATINE from ATP CREATINE. The
reaction stores ATP energy as phosphocreatine. Three cytoplasmic ISOENZYMES have been
identified in human tissues: the MM type from SKELETAL MUSCLE, the MB type from myocardial
tissue and the BB type from nervous tissue as well as a mitochondrial isoenzyme. Macro-creatine
kinase refers to creatine kinase complexed with other serum proteins.;
